Re: Question on shade 3-arguments command

[Ansley Manke <ansley.b.manke@xxxxxxxx>]

Hi Lee,
The 3-argument plot commands let you use a set of coordinates
that do not describe a rectangular grid.  They need to all be in the
same plane; often in X and Y, or in your case X and Z. It looks like
you're specifying an X-Z slice of the variables rho and yrho, and a
Y-Z slice of depth.  Give y=15 for the depth variable, and Ferret
should draw the plot

 shade rho[y=15,l=36], yrho[y=15,l=36], depth[y=15]
